muy interesante, sobre todo por reutilizar partes de otros equipos

Normally I'm not the spelling nazi, but since you did it twice, it's spelled sure, not shure. Nice 'ible by the way.

Hey i stripped a audio jack and found 3 wires not 2 they r red blue and brown should i connect only the blue and red to thee speaker terminals or blue and brown or red and brown pls help me .

Thank u

DOood the sound quality must suck right? (not being offensive) you should hook it up to a small Amp powered buy just 3 1.5volt batteries of any kind.

[tubbsey88]

exactly, just like a little amp from some old computer speakers, thats what i do, then i power it with the 5V rail on my computer power supply

I can't imagine that something that only produces enough power to drive headphones can be enough to drive anything but the most efficient speakers with any kind of volume. A standard headphone jack simply does not throw enough power to produce enough volume. The only way that this could even have a decent volume would be if it has very, very small range of sound.

[rickick]

these work fine it works perfectly i have made another version i also suggest using a headphone jack frokm a set of lager speakers or make your own

I installed something like this for my home renovation.

I built an enclosure that went in the attic to isolate the sound (it's a townhouse) and when it came time to test, I got antsy and hooked it up directly to the headphone output of my 4G iPod, Sansa Express, and Creative Zen Sleek.

They all drove the speaker loud enough for it's intended purpose even though they're probably not the most efficient. Surprisingly, the iPod was able to drive it the loudest although I had to take it down a few steps from max to keep it from distorting noticeably.

You'd be surprised what you can get out of just the headphone output (not the line out).

my 8gb zen has enough power to drive external spkrs

[rickick]

Like i have mentioned before, it all depends on what kind of speakers you use.

[drew.adc]

yes, but in order to gain volume, you have to sacrifice audio quality.

worked for me took out the bottom and put in a extra speaker sounds alright for my purposes though a little quiet

Nice presentation. But here's a problem that I ran into the hard way. Wiring speakers directly to an amplifier can blow the output of the amplifier if the resistance to the speakers is too low. You might want to research the output resistance required before you hook up the speakers. Sometimes one resistor will do the trick, but first you have to know what size resistor is required. If I had known this I would have avoided the bill from the electronics repair shop.

Thanks. You've probably saved somebody some bucks!

Use a Sonic Impact Class T portable amp... they run on AAs and throw some MASSIVE SOUND for the power. I currently have more or less the same thing on my bike and it breaks noise ordinances on a daily basis. They're also $30 so you can afford to tear it apart. Combine that with a 5AH or so SLA battery and you've got a real Boom Box.

[kn100]

an amplifier here might be handy, will work on it now!

[unowhoiam]

hey would speaker wire work instead of the phone crap?????

[rickick]

sry about that, i havent tried yet. if you did tell me how it went!

[unowhoiam]

nvm ... this is y unowhoiam

[I HACK]

this will hab shit low volume(no amp)

[rickick]

it works for me. it's probably your uh! what are they,oh! yea "sh*t speakers".

[rickick]

works for me

[Crim]

no that didnt help me. maybe you didnt understand what i ment.. but it doesnt matter now. i figured it out anyway. im using a similiar setup with the only difference that mine arent from a tv set :p my cable with jack stripped into 3. and i figured out 2 were for each side/speaker and the third was for powering it all. meh..too much explaining.. i should write an diy for it :p

[Crim]

how did you connect both speakers to the jack from the headphones. when it only splits into 2 lines. to connect to both speakers you'll need 4 lines...

[rickick]

That is the tricky part, once you have your 2 wires strip them both and inside each one you will find 2 even smaller wires , strip them and then connect them to your speakers. hope that was a bit helpfull. Rick,

[rickick]

I HOPE THAT EVERYONE FINDS THIS EASY TO UNDERSTAND!!
